Some of the RF energy emitted by cell phones is absorbed in your body. The amount of energy you absorb depends on many factors, such as how close you hold the cell phone to your body and how strong the signal is. So far, the weight of evidence from animal, cell culture and human studies does not indicate that the energy emitted by cell phones is strong enough to cause serious health effects. Some scientists have reported that cell phone use may cause changes in brain activity, in reaction times, or in the time it takes to fall asleep, but these findings have not yet been confirmed.
Public exposure to RF energy from base stations is at a much lower level than that from cell phones. As long as exposures respect the limits set in Health Canada’s Guidelines, Health Canada has determined that there is no scientific reason to consider base stations dangerous to the public.
Cell phones are designed to operate at the minimum power necessary to connect and maintain a quality call. As a result, the intensity of the RF energy from cell phones is well below a level that would cause health concerns. In addition, cell phones and base stations in Canada must meet regulatory requirements that limit the amount of RF energy they emit. See the section below on “”The Government of Canada’s Role”” for further details.
Although the RF energy from cell phones poses no confirmed health risks, cell phone use is not entirely risk-free. Studies have shown that:
* Using cell phones or other wireless devices can be distracting. Your risk of serious injury may increase if you use these devices while driving, walking, cycling, or doing any other activity that requires concentration for personal safety.
* Cell phones may interfere with medical devices such as cardiac pacemakers, defibrillators, and hearing aids.
* Cell phones may also interfere with other sensitive electronic equipment, such as aircraft communication and navigation systems.
